This is Barnes & Noble's classic paperback series that can be found on their website for $7 - $10 each, depending on the title -
B&N Classic Paperback Series [barnesandnoble.com]
I found a display of these paperbacks in several B&N stores marked 2 for $10 (see attached images). These appear to be better quality paperback copies of classic titles including Jane Eyre, A Tale of Two Cities, Pygmalion, The Jungle, The Odyssey, Anna Karenina, etc, etc.
At $5 each for better quality paperbacks of classic titles, it's a decent deal.
